lublana

Answer:

Slope of linear  graph function will be constant.

Step-by-step explanation:

Linear function graph:The equation of linear graph function is given by

\(f(x)=mx+b\)

The degree of linear graph function is one.

Differentiate w.r.t x

Then, we get

\(y'=m\)

Slope of linear function is m.m is constant.

Therefore, if  a graph is graph of linear function then it will have constant slope m.
